Internal server Error trying to Compress or Protect a file

Hi everyone, I'm getting this error from the PDFServicesSdk for NodeJS:

Exception encountered while executing operation ServiceApiError: An Internal Server Error has occurred.; transactionId=nvbyhAvF2nyXcyUsuGwZL2E1dJb5CFiI

}

I think it has something to do with the file because it only happens for some files.

Thanks,
